Application filed May 8, 1911. Serial No. 625,706.

provide improved mechanismfor said purpose, calculated to take secure hold of and feed binding-paper forward, and this without liability. of causing retrograde movement of the binding-paper, which at ,the .time of said feeding is moist and gummed at its underside, and the consequent interference with the operation of the machine as well as loss of binding-paper.

With the foregoing in mind, the inventi n will befully understood fromthe following description and claims when the same are read in connection with the drawings, accompanying and forming part of this.- specification, in which:

Figure 1 is a sideelevation of my novel mechanism, with the side guide wires partly ing-paper.

broken away. Fig. 2 is a horizontal section taken in the plane indicated by the line 22 of Fig. 1, and also showing parts of the side.

guide wires broken away. Fig. 3 is a transverse section taken in the plane indicated by the line 33 of Fig. 2, looking toward the right.

Similar letters designate corresponding parts, in all of the views ofthe drawings, referring to which: i

A is a base plate, designed to be fixed in suitable manner with respect to the frame of a box staying machine (not shown). I

B is an upright, longitudinally slotted guide plate fixed with respectto said base late. P C C are the side guide wires for the bind- D is the longitudinal-central wire that 00- operates with the side wire in the guidance of the binding-paper.

E is a rectilinearly-movable carriage, disposed at one side of the plate B and having a portion a disposed in the slot b thereof, and also having studs 0 disposed laterally at the rear side of the plate B. 'F is a wear plate loosely mounted on said studs and arranged against the rear side of the plate B.

G is a bowed spring secured on the studs 0 and serving to yieldingy hold plate F against the plate B with a view to preventing lateral play of the carriage E. v, I H is an angle plate fixed with respect to the frame formed by the plates A andfB.

I is a vertically swinging rock arni', ful

crumed at d on the carriage E and carrying a jaw J designed to grip the upper side of a binding-paper, and K is a bar designed to be actuated from any suitable working part ;(not shown) of the box staying machine. These parts, with the exception hereinafter noted, may be and preferably are of the ordinary constructionwell known in .the art.

I would have it understood, however, that the said parts may be ofany other construction consonant with the purpose of my invention without involving departure from the scope of the same asdefined in the claims appended.

In furtheranceof my invention I provide the rock-arm I with a cam or tappet M, and I also provide a vertically-swinging plate N, pivoted at e to the opposite side of'the carriage E, with reference to the guide plate B, and having a recess f in which the ,said cam or tappet M of the rock-arm I is disposed, and a jaw P carried by and disposed laterally to the plate N, and designed to grip the underside of the binding paper.

In practice'as the carriage E is, through the bar K, moved toward the left, Fig. 1, the jaw J is moved down against the .binding paper, and atthe same time the cam or tappet M moves the plate N and the jaw P upward, with the result that the binding paper is securely gripped between the jaws and the paper is positively moved or' fed in said direction. On the back movement of the carriage Ei. 6., from left to right, the bar K swings the arm I and raises the jaw J, while the cam or tappet M depresses the plate N and thereby moves the jaw P downward. In other words, both jaws are positively moved out of engagement with the binding paper, and hence there is no liability of the binding paper, which as before stated is then in a moist state and gummed at its underside, being carried backward b1,
